Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639072, here are decompositions:

61 + 8639011 = 8639072
73 + 8638999 = 8639072
139 + 8638933 = 8639072
163 + 8638909 = 8639072
181 + 8638891 = 8639072
223 + 8638849 = 8639072
229 + 8638843 = 8639072
439 + 8638633 = 8639072

Showing the first eight; more decompositions exist.
